Thank you for choosing this instrument from TFA.

1. Before you start using it

•

Please make sure to read the instruction manual carefully.

This information

will help you to familiarise yourself with your new device, to learn all of its func-
tions and parts, to find out important details about its first use and how to

•

Following and respecting the instructions in your manual will prevent dam-
age to your instrument and loss of your statutory rights arising from defects
due to incorrect use.

•

We shall not be liable for any damage occurring as a result of non-following
of these instructions. Likewise, we take no responsibility for any incorrect
readings and for any consequences which may result from them.

•

Please take particular note of the safety advice!

•

Please keep this instruction manual for future reference.

2. Field of operation and all the benefits of your new instrument at a glance

• For contact-free measuring of surface temperature even of hot, hazardous, or

hard-to-reach objects.

3. For your safety

• This product is exclusively intended for the field of application described above.

It should only be used as described within these instructions.

• Unauthorized repairs, modifications or changes to the product are prohibited

and might result in dangerous laser radiation.

• The product is not recommended for taking body temperature.

Caution!

Risk of injury

• The product is equipped with a class 2M laser. If the sign on the device is not

written in the language of your country, please affix the sign below onto the
device.

• Do not point the laser beam at mirrors or other reflective surfaces. The uncon-

trolled reflected beam may strike people or animals.

• Do not aim too close at hot or dangerous targets.
• Keep this instrument and the batteries out of the reach of children.
• Batteries contain harmful acids and may be hazardous if swallowed. If a battery

is swallowed, this can lead to serious internal burns and death within two
hours. If you suspect a battery could have been swallowed or otherwise caught
in the body, seek medical help immediately.

• Batteries must not be thrown into a fire, short-circuited, taken apart or

recharged. Risk of explosion!

• Never use a combination of old and new batteries together, nor batteries of dif-

ferent types.

• Low batteries should be changed as soon as possible to prevent damage

caused by leaking.

• Wear chemical-resistant protective gloves and safety glasses when handling

leaking batteries.

Important information on product safety!

• Do not place your product near extreme temperatures, vibrations or shocks.
• Protect the unit from large or abrupt ambient temperature changes.
• Do not leave the unit near objects of high temperature.
• Do not immerse the unit in water. Water can penetrate and cause malfunction.

Protect it from moisture.

• Check the housing before using the device. Do not use the device if it seems to

be damaged. Check for cracks or missing plastic parts.

• Steam, dust, smoke, etc., can prevent accurate measurement by obstructing the

unit’s optics.

EMC/RFI

• Protect the unit from EMI (Electro Magnetic Interference) from induction

heaters and microwave ovens and Electro Static Discharge. Readings may be
affected if the unit is operated within a radio frequency electromagnetic field
strength of approximately 3 volts per meter, but the performance of the instru-
ment will not be permanently affected.

4. Use

• Press and hold the measuring button to activate the measuring process.
• The backlight is automatically activated.
• The circular laser allows you to target the center of the area to be measured.
• Release the measuring button.
• On the display appear HOLD and the latest measured temperature for about 15

seconds.

• The maximum value (MAX appears on the display) will be displayed during the

measurement.

• Press the °C/°F button and you can change between Celsius (°C) or Fahrenheit

(°F) as temperature unit.

• When the instrument is not used, it will automatically switch off after 15 sec-

onds.

5. Distance, Spot Size, and Field of View

• As the distance (D) from the object increases, the spot size (S) of the area

measured by the unit becomes larger a ratio D:S = 12:1 (e.g. 120 cm distance =
10 cm spot size). To get the most accurate temperature reading, aim at the tar-
get as near as possible.

• Should the distance be too great, there is a risk that the temperature has also

been taken outside the aimed target.

• The circular laser helps to aim at the exact area to be measured. The laser circle

and the measuring spot are congruent at a distance of 2 m.

Please take note of the following:

• Not recommended for use in measuring shiny or polished metal surfaces

(stainless steel, aluminum, etc.).

• The unit cannot measure through transparent surfaces such as glass or plastic.

It will measure the surface temperature of the glass instead.

BEAM - Infrared Thermometer

ATTENTION – LASER CLASS 2M

Never look directly into the laser beam.
